Service bulletin N242438501-02
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Certain 2024 MY Chevrolet Silverado and GMC Sierra vehicles with a 6.6L diesel engine have an Engine Control Module (ECM) that may not properly diagnose, may not set Diagnostic Trouble Codes (DTCs), or may not illuminate the Malfunction Indicator Light (Check Engine Light) if certain fault conditions of the Selective Catalyst Reduction (SCR or NOx) catalyst occur. Dealers are to reprogram the Engine Control Module (ECM) and Transmission Control Module (TCM).

Listing a model year does not mean every vehicle of it is concerned: the document says which.
